Extraction Method of the Contrast Feature of Ship Wake Images

Abstract:

Since how to evaluate the ship wake images quality quantitatively and effectively, and achieve the purpose of the extraction of ship wakes optical signal characteristics rapidly, is an important base task for the ship optics-wakes elimination technology now. The method about quality evaluation of ship wake images is studied in this paper based on the contrast model. According to the characteristics of the obvious contrast between wake area and seawater background area in ship wake images, this paper uses the contrast parameter as the index of wake image quality evaluation, and also as the characterization of the strength of ship wakes optical signal characteristic. An experiment about the extraction of contrast feature and its results show that the contrast parameters can not only reflect the subjective visual perception of the human eye on the wake images actual quality, but also better reflect the application essence of the wake image processing. And the contrast parameters can describe the intensitys changing rules of ship wakes optical signal characteristics reliably and quantitatively.
